sept. 24, 1935. J. c. SH01-m PIPE Filed March 8, 1933 Patented Sept. 24., 1935 h UNITED ,STATES PATENT OFFICE Jenn c. snmvslmeeooa, vom Applicaties ma 8,1933, sem Nn. 66u25 tes to pipes, and has for its general object to produce a pipe which can be cleaned in a most. effective manner and which will be provided with means whereby the draft Tl through the bore of th'e stemmay be conveniently This inventionl rela and readily controlled in accordance with the 4quality of the tobacco used in the pipe and the taste of the particular smoker. Further and more limited objects of the invention will be set l0 forth at length in the specification and will'be realized through the construction shown in the drawing, wherein Fig.v 1 represents a central'longitudinal sectional view through a pipe constructed in accordance with my invention; Fig. 2 a 'i6- and a portion ofthe stem of said pipe; Fig. 3

. `a detailin section corresponding tothe line 3-3 of Fig. 2; Fig. 4 an elevation of the means for supplying cool lair to the bore of the stem of said pipe; and Fig. 5 a central longitudinal sectional view of lsaid pipe, showing themanner in i which a cleaner may be employed therewith.

` Asv is .well known to smokers, there is a tendency for liquid to collect in the bottoms of the i-bowls of pipes, which liquid not only gives oiI nicotine, but also is liable to enter the bore of the stem, with consequent discomfort to the smoker. Furthermore, as is also well known, vsome smokers prefere to use a comparatively an. strong and moist tobacco with the production of what is known as a heavy smoke, while others prefer to use a relatively mild anddry tobacco,

with the production of what isknown as a light'j smoke. lStill further, some smkersprefer a pipe v'all and a grade ofY tobacco which will produce a relaable objects hereinbefore recited, and to accomplish these results by the use of a single pipe which is equipped with such invention.

- Describing the various parts by reference chari501` acters, l denotes the bowl and Zvthe stem of a pipe, the stem being provided with a bore consisting of a section I, the said section'merging adjacent to the bore with a section l* of slightly f greaterV diameter. Thel outer side of the bowl I5: (the side remote from 'the stem 2) is .provided detail in central longitudinal section of the bowl objectionable features and to realize the desir- 4 Claims. (ci. 131-12)A with a bore section ltherethrougvh', which isv preferably of the same diameter as the section 3*. It will be noted that the bottoms of the bore sections 3" and 3b are substantially ush with the bottom of the bowl I. ,il

Mounted in the bore sections 3' and 3b and extending' across the bottom of the chamber oi' the bowl of the pipe is a tube l. which tube is preferably constructed of a metal capable of becoming heated quickly, such as aluminum. The'in-I 10 ternal diameter of the tube l is equal to the diameter of thebore section 3 whereby the interior of the tube constitutes a continuous extension of the bore section 3 across the bottom of the chamber of the bowl and` through the' l5 wall thereof which is remote from the mouthpiece. This tube is provided with a narrow slot 4 in the top thereof and with corresponding slots 4b in opposite sides thereof and above the bottom of the tube and the bottom of the bowl. slots are sufficiently narrow to prevent clogging of theldraft through the bore 3 by packing to- 1 bacco in the bowl. The slots 4P are. located above the bottom of the bowl to prevent or limit access thereto of anymoisture that may ltend to ac- 25 cumulate in the bottom oi the bowl, although such accumulation is reduced toaminimum by the-heat received and dissipated by the tube 4. The aggregate areas of the slots l" and 4h" will be suillcient to satisfy one desiring a "heavy .30 smoke.. However, in order to accommodate thel pipe for the use of those desiring varying degrees of a lighter smoke, there is itted within the tube 4 a tubular damper 5 having slots 5 and 5b preferably 'of the same width and length as the slots 35 4* and 4b, respectively, and adapted to register more or less therewith, accordingly as the tube 5 is rotated by means of the integral head I which is formed therewit and which vabuts against the side of the'bowl w ch is remote from` 40 the stem and closes the outer end of the bore I? and prevents access of outside air to the end of 'head 6 is preferably circular in outline and is shown as formed integral with lthe tubel 5. 4,5

In order to enable the smoker to vary the warmth of the smoke, I have provided the head i with a plurality of openings 6 therethrough and have mounted on the said head, by means of .a central stud or rivet l, a rotary damper 8 having 50 `openings 8* therein and adapted tobe brought more or less into register with the openings By rotating this damper more or` less, air may be admitted through the openings 6 with correspondingcooling ot the smoke and neutralization 6 Theseao or dilution of the carbon monoxide contained therein.

Due to'the construction and arrangement of the parts as thus far described, I am enabled to 5 produce a pipe which will accommodate the tastes of all classes of smokers, so far as ,the quality and temperature of the smoke is concerned; also to neutralize or dilute more or less the carbon monoxide content of the smoke as well as to vary the temperature of the smoke; also to prevent the bore of the stem from becoming clogged by packing tobacco in the bowl as when it is desired to have a prolonged smoke with one filling.

There is another important result which may apparent more particularly from Fig. 1. Should any liquid enter the tube l and the bore 3, this liquid may be effectively removed without leaving any residual part of such liquid in the portion of the bore which is adjacent to the mouthpiece. Furthermore, I am enabled to accomplish this result with the utilization of the entire length of the cleaning element which is usually employed for'pipes. One of these elements is indicated at 9, and is preferably of the usual type of cleaning brush, consisting of central wires 8 having entwined therewith fibrous absorbent material 9b. By removing the tube 5, this brush can be inserted into the mouthpiece end of the stem and, being longer than the bore 3, can be pushed and pulled entirely through said bore and the tube 5L It will be noted that, due to my construction, the bore, comprising the tube 4, and the slots therein are subjected to the cleaning action of the entire length of the brush and that, because it is not necessary to reciprocate the brush, none of the liquid material that may adhere thereto need be carried thereby into the portion of the bore at or adjacent to the mouthpiece. The tube 5 may be cleaned when removed, either by a brush or by any other -convenient cleaning means.

Furthermore, there is no necessity for using a two-part stem (although such a stem is shown herein), as there will be no occasion for removing an outer stem section for cleaning purposes.

It will be evident that the tube Q constitutes a 4part of the bore, whereby the said bore extends throughout the length of the stem and entirely across the bowl and through the wall thereof which is remote from the mouthpiece; that, by providing this extended bore with'a removable closure, the bore may be cleaned most effectively and without bringing any of the moisture which may be therein to or adjacent to the mouthpiece. Also that no trap is provided between the bowl and the mouthpiece for the accumulation of any liquid. In addition, because of the other features of construction which have been described herein, I am enabled to, accommodate a pipe equipped with my invention to various grades of tobacco and to varying tastes of smokers.

Having thus described my invention, what I claim is: l l

1. A pipe comprising'a bowl and a stem, the said pipe being provided with a bore section extending through the said stem from the outer end thereof to a point adjacent to the bottom of the bowl and having a second bore section of slightly greater diameter than the first bore section and a third bore section of substantially the same diameter as the second bore section and extending through the wall of the bowl opposite said stem. the upper portions of the second and third.
